Texas Instruments ADS5296AEVM

Overview

ADS5296AEVM from Texas Instruments is an evaluation module for the ADS5296A 12-bit, 8-channel analog-to-digital converter, supporting up to 80 MSPS in non-interleaved mode or 200 MSPS in 4-channel interleaved configuration. It features LVDS serial output (up to 1000 Mbps), programmable FIR/IIR digital filtering, and low-frequency noise suppression mode - enabling high-fidelity signal capture in ultrasound imaging front-ends and multichannel data acquisition systems.

Technical Context

The ADS5296AEVM implements a hardware platform to evaluate the ADS5296A ADC in both 8-channel 12-bit (80 MSPS) and 4-channel 10-bit interleaved (200 MSPS) modes. It provides full access to all 64 pins of the QFN-64 package, including differential analog inputs (IN1_p/n through IN8_p/n), LVDS data outputs (OUT1_p/n through OUT8_p/n), frame/bit clocks (ADCLKP/ADCLKN, LCLKP/LCLKN), and control interfaces (SCLK, SDATA, CS, RESET, SYNC).

It supports configurable serialization (10x/12x/14x), decimation filters (FIR/IIR), channel averaging, and programmable mapping between ADC channels and LVDS output lanes. The board includes on-board clock conditioning, reference voltage generation (REFT/REFB), and power regulation aligned with ADS5296A's AVDD (1.8 V) and LVDD (1.8 V) requirements.

FAQ

What is the primary function of the ADS5296AEVM?

The ADS5296AEVM is an evaluation module that enables hardware validation and performance characterization of the ADS5296A 12-bit, 8-channel analog-to-digital converter. It provides complete signal path access - including all eight differential analog inputs, LVDS data outputs, clocking resources, and digital control interfaces - allowing engineers to verify timing, SNR, SFDR, and digital filter behavior under real-world conditions before integration into final systems.

Does the ADS5296AEVM support both interleaved and non-interleaved ADC modes?

Yes, the ADS5296AEVM fully supports both operational modes of the ADS5296A. It allows configuration for 8-channel, 12-bit sampling at up to 80 MSPS (non-interleaved) or 4-channel, 10-bit sampling at up to 200 MSPS (interleaved), using the INTERLEAVE_MUX pin and onboard jumpers or software control via the SPI interface. Timing diagrams and latency measurements in the ADS5296A datasheet (SBAS631) are directly verifiable on this EVM.

What clocking options does the ADS5296AEVM provide for the ADS5296A?

The ADS5296AEVM supports differential clock input via CLKP/CLKN pins using LVDS, LVPECL, or ac-coupled sine-wave sources (0.2–1.6 VPP). It includes on-board clock conditioning circuitry and provisions for external clock injection. Frame clock (ADCLKP/ADCLKN) and bit clock (LCLKP/LCLKN) outputs are accessible for synchronization with FPGAs or receivers, matching ADS5296A's specified 6x and 12x clock multiplication ratios.

Can the ADS5296AEVM be used to evaluate the ADS5296A's digital processing features?

Yes, the ADS5296AEVM enables full evaluation of the ADS5296A's integrated digital processing block, including programmable FIR decimation filters, IIR high-pass filtering for DC offset removal, digital gain adjustment (0–12 dB), channel averaging, and low-frequency noise suppression (LFNS) mode. These functions are controlled via the SPI interface and validated using the EVM's onboard FPGA-based data capture and analysis tools referenced in TI's ADS5296AEVM user guide.

Is the ADS5296AEVM compatible with standard FPGA development platforms?

Yes, the ADS5296AEVM features a standard 2×20-pin LVDS header compatible with common FPGA carrier boards and TI's TSW1400EVM data capture platform. Its LVDS output format (10x/12x serialized, frame-synchronized) aligns with Xilinx and Intel FPGA transceiver IP cores. TI provides reference HDL code and GUI software (HSDC Pro) to configure the ADS5296A and stream captured data directly into PC memory for spectral analysis and waveform validation.
